Top 7 Roofing Issues We See in Collingwood Homes

At CT Roofing Solutions, we've worked on countless homes across Collingwood and the surrounding areas, and we've come to notice a few consistent roofing issues that homeowners face. With a climate that includes snow-heavy winters, damp springs, and plenty of seasonal transitions, roofs in Collingwood take a beating year-round.

Whether you’re a long-time resident or new to the area, understanding the most common roofing problems can help you prevent costly repairs and extend the life of your roof. Here are the top 7 roofing issues we see most often in Collingwood homes.

1. Ice Dams in Winter

Ice dams are one of the most common and damaging winter-related roofing issues in Collingwood. When snow melts on a warmer part of the roof and refreezes near the colder eaves, it forms a ridge of ice that prevents proper drainage. This forces water back under shingles and into the roof deck, causing leaks and water damage.

Solution: Proper attic insulation, ventilation, and an ice & water shield membrane can dramatically reduce the risk of ice dams.

2. Wind Damage from Storms

Strong winds—especially in the fall and spring—can lift, curl, or even tear shingles off the roof. Once shingles are missing or damaged, your roof becomes vulnerable to water infiltration and further structural problems.

Solution: Regular inspections, especially after storms, can catch wind damage early. CT Roofing offers fast, reliable storm repair services across the region.

3. Clogged Eavestroughs and Poor Drainage

With Collingwood's abundance of mature trees and seasonal leaf drop, eavestroughs (gutters) can quickly become clogged. Blocked drainage leads to overflowing water, which can damage fascia boards, siding, and even your foundation.

Solution: Routine cleaning and optional gutter guards will help keep water flowing freely. We also offer inspection and maintenance packages to keep your system clear year-round.

4. Moss and Algae Growth

Shaded or poorly ventilated roof areas are prone to moss and algae growth, which are not just cosmetic problems. Over time, moss holds moisture against the shingles, leading to decay, rot, and shortened roof lifespan.

Solution: Professional roof cleaning and possibly improving ventilation can help address this issue before it spreads.

5. Premature Shingle Wear

Extreme temperature swings and UV exposure cause shingles to crack, blister, or curl over time. We've seen this particularly in older asphalt shingle roofs that haven't been maintained or upgraded with modern materials.

Solution: Investing in high-quality shingles rated for Canadian climates and scheduling annual inspections can help prevent premature failure.

6. Poor Roof Ventilation

Many homes in Collingwood—especially cottages or older houses—suffer from inadequate roof ventilation. This leads to heat and moisture buildup in the attic, which accelerates shingle damage and encourages mold and mildew growth inside the home.

Solution: Upgrading or modifying your attic ventilation system (ridge vents, soffit vents, etc.) can significantly improve roof performance and energy efficiency.

7. Flashing Failures Around Chimneys & Skylights

Flashing is a critical component for waterproofing areas where the roof meets a vertical surface like a chimney or dormer. Over time, flashing can crack, rust, or become loose, leading to leaks that are often hard to trace until significant damage has occurred.

Solution: During inspections, we always check flashing points and can reseal or replace them as needed to prevent future leaks.
